Limitations
It is not possible to configure the number attribute to be empty for change notice or task template and generated for change notice or task because the template attribute is not set until the create wizard is submitted. Instead, it is recommended to use a generated sequence for both the change notice or task template and change notice or task if a generated sequence number is required for creation of change notice or task.
